If payments are enabled in your Tiger marketplace, you need to define a minimum transaction size—in other words, the smallest amount that an item can be purchased for. PayPal charges a fee for each transaction so does Stripe, and this fee always includes a fixed amount (for instance, in USD, PayPal’s minimum fee is $0.30).
